One of my favorite things about K-dramas are the strong on-screen friendships that warm your heart, but real-life friendships are even better! Did you know that these Korean actors are actually besties even after the cameras stop rolling?

1. Lee Kwang Soo and Song Joong Ki

When these two played BFFs on Nice Guy, it wasn't an act! The two have been close ever since they were on Running Man together, and they are still friends to this day. Reportedly, Kwang Soo is the only celebrity who has been invited to Song Joong Ki's home, and recently, Song Joong Ki used up one of his military leave days to support Kwang Soo at his sister's wedding. 

2. Jung Il WooLee Min Ho, and Kim Bum

Lee Min Ho and Jung Il Woo have been friends since middle school, but they really grew close when they were in a serious car accident while on vacation in 2006. Jung Il Woo also became close with Kim Bum while filming Unstoppable High Kick, and he has said Kim Bum is like a brother to him. The three don't see each other often because of their chaotic schedules, but they often invite each other to events.

3. Han Ye Seul and Jung Ryeo Won

These two have been besties for years, posting photos together on social media back in Jung Ryeo Won's My Lovely Sam Soon days in 2008. More recently, they went on a shopping trip to Paris together.

4. So Ji Sub and Song Seung Hun

Friends for over twenty years, before either of them became famous, these two still take time to hang out. In a 2014 interview, Song Seung Hun hilariously revealed that when they get together for drinks, So Ji Sub's drunk habit is randomly rapping and singing hip hop. I would love to see that!

5. Jeon Ji Hyun and Lee Young Ae

The My Love from Another Star and Jewel in the Palace stars first became acquainted during a commercial shoot, but they ended up staying in touch. When Lee Young Ae's twins celebrated their first birthday in 2012, Jeon Ji Hyun was the only celebrity in attendance.

6. Yoochun and Lee Tae Sung

Although they played bitter rivals in Rooftop Prince, the two actually became close friends on the set of the series, especially when Lee helped console Park after the death of his father. Lee Tae Sung said of their friendship, "We only have to say a few words to each other and we know exactly what the other person is thinking."

7. Kim Woo Bin and Lee Jong Suk

I simply can't get enough of this friendship! I think my favorite moment between the School 2013 costars might have been when Kim Woo Bin made a surprise appearance at Lee Jong Suk's birthday fan meeting, and Lee Jong Suk cried. Awwww!

8. Cha Tae HyunKim Jong Kook, and Jang Hyuk

All born in the Year of the Dragon 1976, these three "Dragon Brothers" have been supporting each other for years, attending each others' movie events, album launches, and other major life events. Real-life besties Cha Tae Hyun and Kim Jong Kook will now appear together in the upcoming series Producer, premiering exclusively on DramaFever on May 15! Is it too much to hope for a Jang Hyuk cameo to make the trio complete?

9. Lee Seung Gi and Lee Seo Jin

These two actors met because they work with the same agency, but now they hang out, spend Christmas together, and go on vacations together. The buddies recently starred side by side in the movie Love Forecast, though their characters weren't exactly friendly.

10. IU and Suzy

IU once described her friendship with her Dream High costar as being like a pair of magnets "because we stick together and drag each other around." Even when they are too busy to meet in person, they try to contact each other often.

11. Won Bin and Kang Dong Won

Even though these two are serious film actors, when they hang out, their hobby is...playing video games! Two two actors reportedly enjoy going to PC rooms to face off online.

12. Lee Jung Jae and Jung Woo Sung

These two have been nicknamed the "Cheongdamdong Married Couple" because they do absolutely everything together, including launching a business. They became friends on the set of the classic 1999 movie City of the Rising Sun, and they have been inseparable ever since.

Awww! Which one of these sweet friendships is your favorite? These aren't all of the K-celebrity friendships out there, so which other ones do you find endearing? Share your thoughts in the comments!
